Description

This project examines the Environmental Impact Assessment (EIA) of the Gwynt Y Mor project on the marine ecological environment, namely the water and sediment quality, areas of conservation interest and marine species including benthic invertebrates, plankton, fish and marine mammals.  This has been undertaken through the review of available literature and, where necessary, undertaking site-specific surveys to provide baseline information on which the assessment of any impacts of the Gwynt Y Mor Offshore Wind Farm project are then based.  It should be noted that impacts of the projecton terrestrial species (including birds) and terrestrial habitats have been accessed for within other reports (e.g. see ERM, 2005) and are not detailed within this report.
